Unplug your computer, then you will find a small battery on the motherboard, this is a small silver disk shape. you need to remove this by pressing the clip to its side, this lets it spring free. you then need to locate the cmos jumper. this is a 3 pin stand off with 2 pins already covered by a plastic sleeve. remove the sleeve and place it over the other two pins, wait a few seccons then put everythinbg back to the way it was. put the jumper back in its origional position and re-attach the battery making sure it is the right way up. plug in your system and give it a try.

a) open or dismantle the computer tower,you will find motherboard, closely observe a silver colored circulated watch battery(looks like circular coins....) try open the battery byusing screw-drivers gently...and wait for few seconds and replacing again in the same way u removed and close the tower and start system , you will some message on balnk screen saying:

CMOS check sum error or some changes are mades try to follow onscreen instructions or press the F1 to continue...thus we can CMOS reset

b) when you start ur system from the begining tab the DEL or F1 or F10 button which will take ur BIOS SCREEN in the bios screen press the button F5 and then press F10 which will show message to save click yes....and ur will start woking .... then CMOS reset...

On your motherboard, take out the CMOS battery for about 30mins then insert it again. Make sure that you are carefully taking it out. CMOS battery is a metallic circle shaped found on your motherboard.

The only way to reset CMOS is to remove the battery on the motherboard. It's a small battery looks like a watch battery, It keeps juice to the motherboard when the computer is turned off so the date and time stay current. Take it out and wait about 10 minutes. Put it back and boot. CMOS will be set to defaults.

I guess everyone working on a computer is familiar with the word BIOS and what exactly it is? Still let me tell that BIOS is intelligent software that enables the system to start. I need not to mention that system here refers to computer. Bios facilitate the booting of a system without human intervention. BIOS is a program that is installed in a hardware chip known as ROM chip.

This single word matters a lot to most of the users who face various problems when their system failed to start normally or make some unusual activities. Each time I visit any technical forum I see a lot many users posting their problem regarding BIOS. I researched on internet about BIOS errors and from my knowledge and experience I am posting this piece of help for those who find themselves helpless in getting a solution to BIOS problems.

Sometimes BIOS itself provide a troubleshooting to most of the problems. When you power ON your system it give beep sound. Checkout some beep codes 1 short Beep indicates System is OK (Acceptance Beep)Continue long Beep tells RAM Problem1Long 3 Short Beep confirms RAM Problem2/3/4 short Beep --its time to Check the RAM & Video Card

By now most of you have found some clue about the problems you are facing. Now learn about POST faults1) K/B Error/ NO Keyboard present·Check the loose cable connector·Cable may be bad (Keyboard)·K/B itself may be bad·Check the physical condition of K/B connector on M/B·If all these are ok & problem is still processed·Than replace the keyboard port2) Floppy disk drive Fail·loose data & power connector of FDD·Data cable may be bad (FDD)·Load the CMOS defaults·Floppy disk drive itself may be bad3) CMOS Checksum error·CMOS battery has gone bad replace it. (Weak)·Check the CMOS jumper it may set on clear·If the entire ok than check the CMOS battery jack, it may be bad

4) Invalid System Disk, Insert System Disk & Press enter when ready/ NTLDR is Missing·Check the root directory; it may be formatted or missing bootable files.·Repair the Windows or Reinstall the operating system.

5) Disk Boot failure, Insert System Disk & Press enter when ready·Hard Disk check in POST Detected or not·If not Detected Check the power cable·Check the Master/Slave jumper setting.·Also check BIOS setting6) Computer gives message: Your computer has a serious problemBack up your data & replace your Hard DiskThis error message is displayed due to the SMART option. This scans the HDD for errors, if it detect the errors than it show the above message. Follow the error message & back up your data on to another drive.I tried to explain most of the problems along with their solutions. There could be a lot more solutions for the problems. Make your own search and try to fix BIOS problems at your own home.Forward this to all those who need help!!SOVI

seems like you might have to open her up and reset cmos. find your manual turn off power remove the 2 pin tab on cmos and place it 1 pin down or up depending on it position wait 10 sec then place back. power on and i hope this will do it

to reset the password, remove the main battery and main power supply, hit the power switch to drain any retained charge. then remove the cmos battery and short out the contacts. the cmos battery is on the right under the panel at the top of the keyboard, which can be popped out by gently levering it up at the edges. the keyboard can then be folded clear, watch for the ribbon cable under it that connects to the motherboard

Hi,Its possible that your cmos settings were changed prior to this problem so as not to display cmos settings options at boot up. Have you tried resetting your cmos settings to fix the problem? You can do this by a jumper which is usually found on the mother board named "clr cmos" (clear cmos). Let me know if this is of help or not.Regards,Graemevm
